True or False, Engineers follow a written list of instructions to solve problems.
FALSE
What is the first step of the scientific method?
Ask a question/make an observation
True or False: The rock cycle shows the circular motion of rocks.
FALSE, the rock cycle shows the breaking down and reformation of rocks through earth processes?
What is the thickest layer of the earth?
The mantle
What is the name for the supercontinent that existed thousands of years ago?
Pangaea
The ____ habitat is found where the ocean meets the land.
Intertidal
What is the term for a "test model" that engineers create to make sure their design works before building the real thing?
Prototype
What is a hypothesis?
An educated guess about what will happen in an experiment, usually an IF/THEN statement.
Name the two processes that turn sediment particles into sedimentary rocks.
Compaction and compression.
What is the inner core made of? Is it solid or liquid?
What moves the tectonic plates? Where do they come from?
Convection Currents, from the Mantle.
The Photic Zone means the _____ zone
"light"
Can you cook a lasagna in the dishwasher? What were two problems you might encounter? (mythbusters)
YES! Takes a VERY long time, can't cook meat inside, doesnt get hot enough.
You make an experiment where you give a runner an energy drink that is supposed to make him/her run faster. What is the independent and dependent variable in this experiment?
Independent variable would be the energy drink, the dependent variable would be the running speed.
What type of rock can turn into metamorphic rock?
All types of rocks.
What layer creates the magnetic field around the earth?
The outer core
Name three minor plates and two major plates.
Minor: Somali, Nazca, Phillipines, Arabian, Caribbean, Coco, Scotia, Juan de Fuca
Name three organisms that would be found in the Open Ocean.
Sharks, Whales, Schooling fish, some Squids (answers will vary)
Name something an engineer would do, or help create.
Answers will vary, anything creative/innovative/requiring a problem to be solved.
Define controlled variable (also sometimes called a constant)
A controlled variable is something you keep the same between experimental groups, and control groups.
What is the name for when sediments are transported from one place to another?
Erosion
______ currents come from the mantle and help move the crust.
Convection currents.
What were the three pieces of evidence that helped Wegener create his theory of plate tectonics.
Plates fit together like puzzle pieces, fossil evidence matched between continents, rock layers matched on continental edges.
True or false, the continental shelf ends once the land reaches the water.
Name three different types of engineers.
Answers will vary, could be nuclear, medical, city/street/architectural, civil, aerospace, technology/software.
You observe that caffeine increases your heart rate when you drink it (makes you FEEL like you have more energy...you dont actually get more energy). You ask a question and wonder whether animals, particularly a goldfish, is affected the same way. Create a hypothesis for an experiment testing this question.
If you give a goldfish caffeine, its heart rate will increase/decrease.
What are the names for molten rock above and below the surface of the earth? Which is which?
Lava is molten rock on the surface, magma is molten rock below the surface.
What type of rock makes up the continental crust? What type of rock makes up the oceanic crust? Be specific.
Granite is continental, Basalt is oceanic.
Name the two men (first and last names) who helped create the theory of continental drift.
Alfred Wegener discovered plate tectonics, and Harry Hess discovered sea floor spreading to support his discovery.
Name three ocean habitats that would be (if not completely, at least partially) found in the Photic Zone
Intertidal, Open Ocean, Neritic
